Bromobenzene was used in the synthesis of four-armed star chain transfer agent, required for the preparation of amphiphilic star graft copolymers. It was employed as organic extraction phase in the Ion pair-based dispersive liquid-liquid microextraction of ultratrace levels of gold in water samples, soils and river sediments.
Bromobenzene can be used as a reactant for the cross-coupling reactions such as Suzuki coupling reaction to synthesize a variety of unsymmetrical biaryls and Mizoroki−Heck reaction to synthesize various substituted alkenes. It is also an effective quencher for the fluorescence quenching of anthracene.
